Lina the Slayer is a ranged Intelligence hero, adept at destroying enemy heroes quickly by delivering massive bursts of magical damage, making her one of the most effective gankers in the game. She possesses immense damaging capabilities all throughout the game, but is very fragile. Two of her fiery spells are her main source of damage, Dragon Slave sends a wave of fire to burn enemies in her path while Light Strike Array stuns them with a concentrated pillar of solar flame. Each of her spells deals great damage early on and has a low cooldown. Her Fiery Soul bolsters her attack and movement speed every time she casts a spell, which gives her scaling damage for the later game. Laguna Blade, her ultimate, is her ace in the hole. Lina fires off a huge bolt of lightning at a single target, dealing colossal damage. Laguna Blade's damage is staggering in early-mid game, and late game is still enough to destroy frail enemy heroes. Dragon Slave, Light Strike Array, and Laguna Blade are incredible flaming nukes that can incinerate her target instantly, and Fiery Soul allows her to transition into a strong and fast physical attacker. Though her power falls from its peak late game, mana-boosting and damage-increasing items can be purchased to keep herself up.
 Recommended items
- Combining Light Strike Array with a guaranteed stun such as Vengeful Spirit's Magic Missile or Sven's Storm Hammer makes Lina a serious ganking force early on.
- Positional items such as Eul's Scepter of Divinity, Blink Dagger, Force Staff or Phase Boots can help you a lot landing Light Strike Array and thus your whole spell combo without relying on other heroes.
- Always cancel the backswing animation after casting your spells, as Lina suffers from long animation times.
- In teamfights it can be very beneficial to quickly focus on low-HP or support heroes, as Lina has very good nuking abilities.
- When paired with Pugna or Shadow Demon, both of whom have percentage-based damage-increasing mechanics; Lina's burst damage becomes gigantic (a sceptred level 3 Laguna Blade will do about two thousand damage alone) to the extent where she can assassinate enemy heroes with a significant gear/level advantage over her.
- If Lina has the basic items she needs; it is wise to augment her physical attack for the sake of Fiery Soul. Almost uniquely among Intelligence supports, Lina's rightclick becomes a serious threat if she attains a level advantage (owing to her enormous Int growth and her passive ability). Some basic items for this build are Daedalus, Eye of Skadi and Monkey King Bar, as well as some form of lifesteal.
- Dagon can be used to nearly double the burst damage of Lina's ultimate.
- Lina's Laguna Blade can hit for around 2500 damage (without factoring in magic resistance) if she combines Aghanim's Scepter and Refresher Orb, granting her enormous nuking power.
- While unmentioned purchasing an Ethereal Blade if the farm is available combined with an Aghanim's Scepter and Lina's naturally high Intelligence gain will give you a perfect combination of survivability through stats, armor and Ghost form and an enormous increase (roughly 2534 not counting the damage from Ether Blast) in damage output allowing Lina to instantly kill most low to average HP heroes provided that she lands all of her spells during the Ether Blast. The slow provided by Ether Blast also comes in very handy in landing Light Strike Array.
- If Lina is tending to be targeted first (this is a very common tendency), some survival-increasing / utility items will be of great use.
- Some players advocate building a Dagon in place of an Aghanim's Scepter, as it is cheaper (though not if upgraded) and ultimately does more damage (through both its active and its bonus to her attack damage). However, Aghs makes her significantly more durable, whereas Dagon does only slightly, and Lina is very fragile. If you think you are unlikely to die very much, Dagon is probably the wisest choice. However, Aghs can be a wise choice if there are some bkb's in the game or if playing against a Lifestealer or a Juggernaut as they both have magic imunity spells.
- For Fiery Soul to take to its peak, cast Dragon Slave, Light Strike Array, and Laguna Blade successively to take the speed-enhancing effect of Fiery Soul to its maximum potential.
- The original Lina Inverse "The Slayer" was modeled after the main character from the novels/anime/manga Slayers where Light Strike Array, Dragon Slave and Laguna Blade are all spells used by the original Lina Inverse.
- Lina's line "Better to burn out than fade away" is a reference to the Neil Young song, "My, My, Hey, Hey".
- The line also appears in the suicide note of Kurt Cobain.
- Though unstated in Warcraft 3, in Dota 2 Lina and Rylai (Crystal Maiden) are sisters in Dota 2 with a bitter rivalry and many unique responses when they encounter or kill each other.
- One of Lina's Batrider responses is a reference to a line in the movie "Fear and Loathing in Las Vegas"
- In older versions of DotA, Lina was a male hero that used the skin of the DotA Invoker. His name was Link Inverse.
